App Tamer tames your processor-monopolizing apps and keeps them from chewing up excessive CPU time and battery life. Powered by a unique AutoStop feature, App Tamer stops each application when you switch away from it — when you return to that app, it restarts automatically!

App Tamer is built around an attractive and clear user interface, designed for managing all your running applications with minimum distraction or frustration. With helpful displays, you can monitor the average percentage of your processor(s) being used by each app, or access a graphical history or your CPU usage. Easily enable AutoStop for any application, or limit it to a certain amount of CPU time.

What’s New in App Tamer

Added an option to keep App Tamer’s window floating above other windows when it’s torn from the menu bar.

Worked around a bug in Mojave that prevented App Tamer from waking background apps when you used a scroll wheel or gesture to scroll their windows without bringing them to the front.

Improved keyboard traversal of the process lists in App Tamer’s window, enabling type-to-select and selection using the arrow keys.

Fixed a bug that could result in App Tamer not keeping Safari awake while it was downloading a file.

Corrected some UI glitches that occurred when the process list updated while you were using it.

Requirements for App Tamer

Intel, 64-bit processor

OS X 10.8 or later

CAN NOT DOWNLOAD: Some probably encounter the following error: This site can’t be reached ...sundryfiles.com’s server IP address could not be found. DNS_PROBE_FINISHED_NXDOMAIN. In this case, please use Google DNS and you will get rid of trouble.

If downloaded file can not be extracted (file corrupted...), please make sure you have downloaded the file completely and don't use Winzip, it sucks! We would recommend using The Unarchiver.

By reason, the App does not work and can not be opened. Mostly, just Disable the Gatekeeper, and you get rid of troubles.
